TestStand 2014 SP1 Known Issues

Overview

This document contains the TestStand known issues that were discovered before and since the release of TestStand 2014 SP1. Not every issue known to NI will appear on this list; it is intended to only show the severe and more common issues that can be encountered.

Each Issue appears as a row in the table and includes these fields:

  • Issue ID - the number at the top of each of the cells in the first column. When you report an issue to NI, you may be given this ID, you can also find IDs posted by NI on the discussion forums or in Knowledge Base articles.
  • Legacy ID (optional) -  If an issue has a legacy ID from NI's legacy/deprecated bug reporting database, you will see it appear on a separate line directly below the Issue ID in the table, or to the right of the Issue ID in the table of contents (separated by a space).
  • Issue Title: in italics - it describes the issue in one sentence or less
  • Problem Description - a few sentences which describe the problem in further detail. The brief description given does not necessarily describe the problem in full detail, and it is expected that you might want more information on an issue. If you would like more information on an issue feel free to contact NI (contact information below) and reference the ID number given in the document.
  • Workaround - possible ways to work around the problem. The workarounds that appear in the document are not always tested by NI and are not guaranteed to resolve the issue. If a workaround refers you to the NI KnowledgeBase, please visit www.ni.com/kb/ and enter that KB number in the search field to locate the specific document.
  • Reported Version - the earliest version of TestStand the issue was reported in. If you discover the issue appears in an earlier version of TestStand than is reported in this field, you can report that to NI (contact information below) to have the field updated.
  • Resolved Version - version the issue was resolved or was no longer applicable. If an issue has not been resolved "N/A" will be reported.
  • Date Added - the date the issue was added to the document (not necessarily the reported date)

Known Issues

IDKnown Issue
.NET Adapter
139737

Return
Cannot create or edit code of a struct using the .NET Adapter
You can use the .NET Adapter to call methods and properties of structs and classes. However, although you can use the .NET Adapter to create or edit code for a class, attempting to complete these operations for a struct results in an error.

Workaround: N/A

Reported Version: 4.0  Resolved Version: N/A  Added: 05/18/2009
354252

Return
An error can occur when you simultaneously modify the invocations of multiple .NET code modules
If you select two or more .NET steps that use the same assembly and class and you then modify the calls within the .NET Invocation control on the .NET Module tab, an error similar to the following error can occur:

Array offset 2 is out of range; range is 0..1

Error Code: -17324, Array index out of bounds

This error is more likely to occur if the invocations of the two selected steps specify a different number of calls.

Workaround: Modify the invocations of .NET steps individually.

Reported Version: 2010 SP1  Resolved Version: N/A  Added: 07/26/2012
202206

Return
Error -17500 occurs when you execute .NET code modules that deserialize types

Workaround: N/A

Reported Version: 3.0  Resolved Version: N/A  Added: 02/05/2013
402888

Return
When you access a .NET property in a child class that overrides set or get, only the override is available
If you use a .NET Adapter step to access a property that overrides the set or get definition of the property in a base class, only the overridden method is available. For example, if you are overriding the set method of a virtual int defined in a parent class, the get method will not be available in TestStand if the child class is specified.

Workaround: Specify the parent class instead of the child class in the Root Class control on the .NET Module tab to access the object. The .NET Adapter still uses the override in this case.

Reported Version: 2012  Resolved Version: N/A  Added: 06/28/2013
406396

Return
Additional Results setting is not respected for elements of arrays within a .NET adapter step
If you enable the option in the Log column of the Parameters Table for one or more individual elements of an array, the Log option for the array itself does not update accordingly. As a result, the array elements do not appear in the Additional Results panel and TestStand does not log them.

Workaround: Enable the option in the Log column for the array itself instead of the individual elements.

Attempting to debug .NET steps from a TestStand UI built with only native debugging results in vague error message
If you are attempting to debug .NET code modules using the TestStand debugging features and you are using a TestStand User Interface built with native-only debugging (managed debugging disabled), TestStand returns the following vague error:


The Step Into operation failed for the following reason: 'Win32 error: 0x8971001e'


In this case, the code module executes correctly, but you cannot debug the code.


Note: This is expected behavior. The error does not correctly indicate what is causing debugging to fail.

Workaround: Ensure that mixed-mode debugging is enabled for any TestStand User Interface in which you need to debug .NET steps to work around this issue.

Expression error will occur when attempting to store a System.Object[] return value from a .NET code module into an array of 64-bit integers in TestStand.
When a .NET code module returns an array of 64-bit numbers as a System.Object[] data type, specifying a TestStand variable which is an array of 64-bit integers in the parameter expression for the return value will result in an expression error during sequence analysis.

Workaround: It is safe to ignore this error. The data is stored correctly in the TestStand array when the sequence is executed.

Cannot specify an underlying data type when passing a variant parameter using the ActiveX/COM Adapter or API in expressions
TestStand can call methods of an ActiveX Automation server with variant input parameters. However, some methods can fail if the underlying data type is not correct. The ActiveX/COM Adapter and API in expressions do not support specifying the underlying data type of variant parameters.

When you use the ActiveX/COM Adapter to call a COM server method and pass a TestStand numeric value to an optional variant parameter, TestStand passes a variant of the VT_R8 data type to the COM server method. If the method expects a VT_I4 data type and the COM server does not handle the case of a different variant data type being passed in, you receive an error.

Workaround: Create a wrapper VI or DLL that converts the variant data type appropriately and call the COM server method directly.

Reference memory leaks can occur when 'Same as caller' VI code module uses LabVIEW runtime and is called from a TestStand STA execution thread
When the TestStand LabVIEW Adapter executes steps using the LabVIEW Runtime, the adapter executes 'Same as caller' VIs using multiple threads, instead of using the TestStand STA execution thread, which can result in reference memory leaks.

Workaround: Pass error wires through the Property Nodes. This approach forces the VI to run these Property Nodes in the same thread (in this case the STA thread) as the calling TestStand thread.

LabVIEW VI absolute path check does not handle PPLs properly
At load time, when the LabVIEW Adapter checks VI paths to make sure they are not pointing to two different copies of VIs with the same name, the code does not properly account for PPLs. If two steps reference a VI with the same name in the same PPL located in different places on disk, the first VI loaded should be used for both VI calls. However, because the function that checks the VI paths does not correctly handle PPLs, an error is generated.

Workaround: Ensure that you only include and invoke one copy of the PPL in your test system. Alternatively, to prevent the error from occurring, you can manually load the PPL from the location on disk that you want to use. You can do this either by calling a dummy VI in the PPL or by using Open VI Reference in a user interface and then leaking the reference.

If you make a change to the value associated with an enumeration constant in the code module, steps that use the enumeration do not reflect this change and continue to use the previous value for the enumeration constant.

Workaround: Recreate any steps that use the enumeration after you make any changes to the values of enumeration constants you have already defined.

Additional results logging setting for parameters in LabWindows/CVI or C/C++ DLL steps update incorrectly when you change how the parameter is passed
If you configure a parameter in a LabWindows/CVI or C/C++ DLL step to be passed by reference and then you enable the Log option in the Parameters Table, TestStand logs both the In and Out values of the parameter. You can configure the logging of the In and Out data independently on the Additional Results panel of the Properties tab of the Step Settings pane.

If you later change the parameter settings such that it is passed by value, then execute the sequence, you will encounter an error similar to the following:

Details: The following error occurred while logging additional result 'x [Out]': Array offset -1 is out of range; range is 0..0.. Error in parameter 1, 'x'.
Error Code: -17324; Array index out of bounds.

This error occurs because the the log setting for the "Out" value is still enabled, despite the fact that it is no longer a valid option.

Workaround: To disable logging for the Out value and prevent the error, you must configure the parameter so it is passed by reference so that the Out logging option is available. After disabling the option, set the parameter back to being passed by value.

Importing a property from a .xls file using a Property Loader step does not import the full property value if the cell contains a comma
If a text cell in a Microsoft Excel spreadsheet has a value with a comma in it, the Property Loader step imports only the text after the last comma and not the full text of the cell. For example, if a cell contains the value 10,11,12,13, the Property Loader step imports only 13. This behavior occurs because the Property Loader step uses expressions to assign values, such as in Locals.myLocal = (10,11,12,13). However, the TestStand expression language uses commas to separate expressions within an expression, so numbers within the parentheses are considered a set of expressions separated by commas. When a series of expressions separated by commas exists within an expression, the result of evaluating the expression is the result obtained from evaluating the last expression. For example, if the last expression is the number 13, the value assigned to the property is 13.

This issue affects the legacy Property Loader step type included in TestStand 2014 SP1 and earlier. It has been resolved in the redesigned Property Loader included with TestStand 2016.

Workaround: Add quotes around the string to force the Property Loader step to consider the text as a string instead of a series of expressions. When you use the Property Loader step to import text properties, the step imports the text as a string automatically.

Running Sequence Analyzer may result in prototype mismatch errors for string arguments in C/C++ DLL code modules
Analyzing a sequence file with the Sequence Analyzer may result in a prototype mismatch error for certain C/C++ DLL call steps with a string argument.

Import/Export Properties dialog generates a null pointer exception if PLPropertyLoader.ini file is corrupted or from an old version of TestStand
The PLPropertyLoader.ini file (<Cfg> directory, default settings for Import/Export Properties dialog) was modified in TestStand 2014 to use the tag PROPERTIES_SQL_STATEMENT instead of STATEMENT_SQL_STATEMENT. As a result of this change, if the <Cfg> directory contains an old version of this INI file, possibly as a result of migrating settings from another machine, a null pointer exception will be generated if you attempt to launch the Import/Export Properties dialog.

Workaround: Delete or rename the PLPropertyLoader.ini file so that it can be re-created.

Windows cannot find TestStandElevatedCommand.exe when you attempt to change the default source code control provider for the system
When you try to change the default source code control provider for the system, you get the error "Windows cannot find 'C:\Program Files (x86)\National Instruments\TestStand 2014\Bin\TestStandElevatedCommand.exe'".

Workaround: If you are trying to change the Source Code Control Provider setting for a workspace, you can first manually configure the station options by following these steps:
  1. Go to Configure»Station Options»File tab»File Format Options and change the format of the workspace file to XML.
  2. Save the workspace file.
  3. Open the workspace file in a text editor and look for the following section:
  4. <SccProviderName classname='Str' valueflags='8'>
    <value><None></value>
    </SccProviderName>
  5. Change the data inside the <value> tags to the SCC Provider of your choice. For example, Perforce SCM would have the following value:
  6. <value>Perforce SCM</value>
  7. If you were previously using the default SCC provider, you might also need to set the <SccUseDefaultProvider> class to false instead of true.

 

Second, you can manually edit the registry. TestStand looks at ProviderRegKey (refer to the Source Control Tab help topic for the location of this registry key http://zone.ni.com/reference/en-XX/help/370052P-01/tsref/infotopics/db_station_opt_source_cont_tab/ ). This key should point to the desired source code control module. For example, the value of this key for Perforce SCM would be: SOFTWARE\Perforce\P4. If the entry does not exist, then create a new string value for ProviderRegKey.

Finally, if you have another version of TestStand, you can copy TestStandElevatedCommand.exe from that Bin directory and place it in the TestStand 2014 Bin directory noted in the error.

A warning can occur when you build a deployment that includes VIs that contain unsupported Microsoft Windows characters
If a deployment contains VIs that use characters that are not valid for Microsoft Windows files, such as the slash (/) or question mark (?) character, and you enable the Output VIs to Packed Project Library option in the LabVIEW VI Options dialog box, the TestStand Deployment Utility returns a warning similar to the following warning when building the deployment:

Warning: Cannot update VI Path:
Step '<stepName>', sequence '<sequenceName>', sequence file '<sequenceFilePath>'

If you install the deployment on a target computer, the step the warning references does not not execute.

This issue occurs because the paths for VIs contained within a packed project library must use only valid Windows filename characters, which is not the case for VIs within LLBs or LabVIEW libraries.

TestStand Deployment Utility may generate incorrect relative paths when code module files are set to install to a separate base directory from the calling sequence file
When you configure a code module to install to a separate base directory from its calling sequence file, the TestStand Deployment Utility may create a path relative to the base directory, even if that path is not included in the TestStand search directories. This action will lead to an error in the deployed system since TestStand is unable to find the code module file.

Workaround: Complete the following steps:
  1. Use the code module path fields in the calling step to find the base directory TestStand uses to retrieve the affected file. This directory is typically a custom search directory. For example, if your code module is located at "C:\Program Files\myCompanyDir\code\module.vi", and the relative path specified in the calling step is "code\module.vi", then the base directory is "C:\Program Files\myCompanyDir".
  2. Add a new search directory, corresponding to the base directory found in the previous step, for the deployment image path. The deployment image directory is specified on the System tab of the Deployment Utility. For example, if the base directory is "C:\Program Files\myCompanyDir", then create a new search directory "&lt;Image&gt;\ProgramFiles\myCompanyDir" (where &lt;Image&gt; is the absolute path to the deployment image folder you specified in the Deployment Utility). Use the existing image directory to verify that the equivalent base path is correct. Move this new directory to the top of the search directories list. Repeat this step for each unique base path.
  3. Delete all files from the deployment image directory to prevent the deployment utility from finding the files in the image directory while analyzing the source files.
  4. Rebuild the deployment and verify that the paths to the affected code modules in the image directory are the same paths as those to the source files.

If the service is not available, TestStand returns the error "The TestStand service did not start up promptly." The TestStand Service is required for this external environment setup to allow non-administrator users to properly configure these environments.

The TestStand Service can sometimes be delayed while launching because a previous service hangs when starting. For example, the Windows Workstation service might hang for a few minutes on startup when trying to reconnect to mapped network drives if the drives are not immediately available. This can cause the TestStand Service to be unable to start, and if a TestStand User Interface is launched before the service starts, TestStand returns this error.

Workaround: Generally, you dismiss the error dialog box and continue to use TestStand normally, as long as you do not require the external environments to be configured.

To remove the error, try to determine the offending service that is delaying the TestStand Service from starting, and see if you can correct the source of the slow start. You can also delay the launching of the offending service by marking the service as manual startup, and adding a command to the startup group to start the service after other services have been started.

Calling the Module.CreateCode or Step.CreateCode methods on a .NET step or module returns an error if the methods are called from a non-STA thread
The Module.CreateCode and Step.CreateCode methods must be called from a Single Threaded Apartment (STA) thread if you are trying to create .NET code. If you do not call these methods from an STA thread, TestStand returns the following error: "Error -18500: An error occurred during Visual Studio automation: The message filter indicated that the application is busy."

Workaround: Most development environments initialize a UI thread to be an STA thread, so calling these methods from the UI thread is usually safe. Otherwise, you must manually initialize a thread to be STA, and the procedure differs with each environment.

  • The selected step is an instance of a step type that specifies a LabVIEW Edit substep, and the substep code module contains an ExpressionEdit control.
  • You launch the Edit substep for the selected step using the context menu while the Module tab is active on the Step Settings pane.
  • You attempt to modify, add, or remove a property through the VariablesView window of the ExpressionEdit control in the Edit substep code module.


Changing the value or creating a property by right-clicking the expression do not cause the hang.

TestStand User Interface developed with LabVIEW Actor Framework hangs
When creating a TestStand User Interface using the LabVIEW Actor Framework, LabVIEW 2012 and earlier might hang if actors that contain TestStand UI Control references are initialized while other actors are initializing. This issue does not occur with LabVIEW 2013 and later.

Workaround: This issue has been resolved in LabVIEW 2013 and later. If it is not possible to upgrade, use synchronization to ensure that actors that contain TestStand UI Controls are not initialized while other actors are initializing.

The ListBox UIControl does not correctly refresh data when connected as an ExecutionList of Execution View Manager.
When creating a TestStand UI using a TestStand ListBox that is connected to an ExecutionList of the Execution View Manager, the control does not always show the correct list of executions. This problem is more noticeable for user interfaces that use the batch process model.

Workaround: Complete either of the following to work around this issue:
  •  Use a ComboBox.
  • Implement the ExecutionList functionality with a ListBox in the native language of the UI.

Return
The LabVIEW Full-Featured User Interface opens in editor mode by default.
When launching the Full-Featured User Interface directly, instead of through one of the shortcuts, it opens in editor mode instead of operator mode. This requires a license other than the base deployment license.

Workaround: Launch the executable with the /operatorInterface command line flag. Alternatively, change the "IsEditor" property to False from the Property Browser of the Application Manager control and rebuild the executable.
